I have tried their Soft baked Nantucket and Captiva Dark Chocolate Brownie and i really like the texture of it.It's sticky (or chewy),you can almost fold it and it'll bend rather than break.I don't know if i call dense or not but in the inside, there's no evidence of any air pockets that come from creaming method at all.
I try to mimic it at home but can't achieve the same result. My cookies came out cakey and thick. for more info, I used melted butter and high brown sugar ratio, 1 egg+1 yolk and i used AP flour.
